对于无线传感器网（WSN）,提出了基于位置服务器树的移动汇聚点（Sink）的位置管理与路由协议LSTLMRP（Location Server Tree based Location Management and Routing Protocol）。当汇聚点移动时,它只需对它的局部位置服务器树或整个位置服务器树,而不是对大范围或整个网络更新它的位置信息。对于传感器将数据传给汇聚点的路由,LSTLMRP也有新方案。理论分析与仿真显示LSTLMRP与其他协议相比,大大减少了汇聚点位置更新的平均能耗;减少了传感器传送数据至汇聚点的能耗;也解决了传感器能量消耗不平衡问题,这个协议也很适合于大规模或密度高的WSN。 

This paper proposes a new protocol LSTLMRP(Location Server Tree based Location Management and Routing Protocol) for mobile sinks in wireless sensor networks. As sink moves, it only updates its location information in local or whole location server tree, it does not update its location information in large range or whole network. Also LSTLMRP has a new scheme on route to mobile sink. Theory analysis and simulation show that LSTLMRP consumes less energy for location update than other protocols, solves the unbalance problem of sensor energy consumption, and also it decreases greatly the data delivery cost to mobile sink. It is very adapt to large scale or high density WSN (Wireless Sensor Network).
